I’ve recently updated my 5c to iOS 9.0.1, but since then something is chewing hell out of my battery life (compared to before).

Anyone else experienced this and know a fix/what to delete, disable etc?

Thanks-in-advance.

I’ve had the opposite, my battery life has increased.

You can go into settings-battery and see what is using power by %

My iPhone 6 on 9.0.1 was fine, my 6S is getting through it quickly post update so suspect there may be something going on.

Use the battery usage monitor to see what the phone thinks is using a lot.

There’s a function in settings, battery that will tell you whats eating it up, Facebook 31% on mine 3 hours in the background running, Home and lock screen somehow uses 14%, at least you will see what apps to switch off etc..
